+🔥 1. Running Locally (Development Mode)
+Install Go
+
+Ubuntu / Debian:
+
+sudo apt update
+sudo apt install -y golang-go
+
+
+Verify:
+
+go version
+
+Run the app
+
+Inside the project folder:
+
+cd Fitnes-tracker
+DATABASE_URL=./fitness.db go run main.go
+
+
+Open in browser:
+
+👉 http://localhost:8080
+
+Local DB file will be created as:
+
+./fitness.db
+
+🐳 2. Running with Docker (Recommended)
+
+Make sure Docker + docker-compose are installed:
+
+sudo apt install -y docker.io docker-compose-plugin
+sudo usermod -aG docker $USER
+newgrp docker
+
+Create external DB directory
+mkdir -p fitness-data
+
+Fix permissions so container user (UID 1000) can write
+sudo chown -R 1000:1000 fitness-data
+sudo chmod 775 fitness-data
+
+Build the Docker image
+docker compose build
+
+Start the app
+docker compose up -d
+
+
+Check logs:
+
+docker compose logs -f
+
+
+You should see:
+
+Using database file: /data/fitness.db
+Listening on :8080 ...
+
+
+Open:
+
+👉 http://localhost:8080
+
+🔧 3. Docker Compose Explained
+
+Your docker-compose.yml:
+
+services:
+  fitness:
+    build: .
+    container_name: fitness-tracker
+    restart: unless-stopped
+    environment:
+      - DATABASE_URL=/data/fitness.db
+    volumes:
+      - ./fitness-data:/data
+    ports:
+      - "8080:8080"
+
+What it does:
+
+Mounts ./fitness-data → /data inside container
+
+SQLite DB stored on host: fitness-data/fitness.db
+
+App always restarts unless manually stopped
+
+Binds port 8080 (browser UI)
+
+👤 4. Running container as UID 1000:1000
+
+The app inside the container runs as a regular Linux user (not root).
+This avoids permission issues and is safer.
+
+To check container UID/GID:
+
+docker exec -it fitness-tracker id
+
+
+Expected output:
+
+uid=1000(appuser) gid=1000(appuser)
+
+
+If permissions are wrong, fix host directory:
+
+sudo chown -R 1000:1000 fitness-data
+sudo chmod 775 fitness-data
+
+📦 5. Rebuilding & Updating
+
+Whenever you modify Go code:
+
+docker compose build
+docker compose up -d
+
+
+If you want to clean old images:
+
+docker system prune -f
+
+📤 6. Production Setup (Traefik Support)
+
+To put behind Traefik:
+
+Add labels inside docker-compose.yml:
+
+labels:
+  - "traefik.enable=true"
+  - "traefik.http.routers.fitness.rule=Host(`fitness.rozic-dev.com`)"
+  - "traefik.http.routers.fitness.entrypoints=websecure"
+  - "traefik.http.routers.fitness.tls.certresolver=letsencrypt"
+  - "traefik.http.services.fitness.loadbalancer.server.port=8080"
+networks:
+  - traefik_default
+
+💾 7. Backup
+
+Just back up the fitness-data/ folder:
+
+cp -r fitness-data fitness-data-backup
+
+
+Or tar it:
+
+tar -czvf fitness-backup.tar.gz fitness-data/
+
+📚 8. Git Instructions
+Set your identity once:
+git config --global user.name "Dejan R."
+git config --global user.email "dejan@example.com"
+
+Useful Commands
+git add .
+git commit -m "update"
+git push
+
+.gitignore (already included)
+*.db
+fitness-data/
+
+
+DB files will never pollute your git history.
